Case Study: Credijusto tames network complexity and scales faster with Pulumi

Credijusto Taming Network Configuration Complexity

Credijusto, a fast-growing SME lending company in Mexico, needed a better way to manage a highly complex hybrid cloud environment as its engineering team scaled. The company was moving from legacy tools like Terraform and CloudFormation to support an AWS-based architecture that included ECS, EKS, VPC networking, and compliance controls, while also needing consistent standards across rapidly changing infrastructure. Pulumi was selected to help the DevOps team use familiar programming languages to manage infrastructure more efficiently.

Using Pulumi, Credijusto standardized and simplified network configuration, migrated to Amazon EKS, and managed AWS resources such as Lambda and RDS with code. Pulumi Policies also helped enforce tagging, naming, and metadata standards across teams. The results were substantial: Credijusto reported a 90% reduction in network configuration code, improved scalability and reliability, faster infrastructure updates, and better visibility into changes across environments.
